DETAILED DESCRIPTION OF THE DRAWINGS Referring now to the drawings more in detail, a portable copying device 10 according to the invention is shown in FIG. 1 thereof. The device 10 is shown in an assembled condition, thus only the carrying case 12 thereof is visible in FIG. 1. The carrying case 12 appears as an ordinary attache or the like case, including a, lower section 14 and a lid or cover section 16, hingedly mounted on one side thereof to the lower section 14 and held securely thereto at the opposite side thereof by clasp 21. The carrying case also includes a handle 18 for transporting the copying device. I

The copying device 10 is shown in FIG. 2 after the lid'or cover 16 has beenswung into an open position. The lid 16 may be entirely removed from the base portion 14 of the carrying case, or it may be hingedly mounted thereon as shown in the figure.

Upon removalof the cover 16, a plate 20 is revealed. The plate 20 includes a flat or planar center section 22, and a pair of side flanges 24 integrally formed with the center section 22 and bent at an acute angle to the plane thereof. The relation between the flanges 24 and the center section 22 can be more clearly seen in FIG. 3. Mounted on each of the flanges 24 of the plate 20 is a clamping strip 26, which is hingedly mounted at one side thereof to the outwardly extending side 28 of flange 24. The hinge 30 is spring loaded so that the clamping 5 member 26 is held nonnally against a corresponding flange 24 of the plate. As is shown in FIGS. 2 and 3, a downwardly-bent edge flange 32 of each of the clamping strips 26 is provided for retaining a sheet of paper, or a master reproduction copy on plate 20.

Upon the removal of the plate 20 from within the lower portion 14 of carrying case 12, (FIG. 4) there is revealed a support frame 34 mounted in the lower section 14 of the carrying case 12. Mounted at the sides of support frame 34 is a pair of hinged clamps 36 each of which includes a hinge 55, a lower stationary portion 54 and an uppermovable portion 57. The lower portion 54 includes a plurality of apertures 59 extending therethrough while the upper portion 57 includes thereon, a plurality of spaced-apart mounting studs 38 to be inserted into the last-mentioned apertures. Held in place between the clamps 36 (FIGS. 4 and 6) is a sheet of master copy reproducing paper 40. The clamps 36, unlike clamping strips 26 mounted on plate 20, are not spring loaded, but instead are held in a closed position by means of pivotally mounted locking members or dogs 42. A locking member or dog 42 is shown in greater detail in FIG. 5 of the drawings, and comprises a body 44 which is pivotally mounted to the base'46 of lower section 14 by means of a pin 48 and includes extending therefrom an arm 50 which can be swung about to retain clamp 36 in a clamped position on the master copy sheet 40 held at the center section of frame 34.

FIG. 7 shows the copying device 10 with the clamps 36 in an opened position. The master copy 40 is rolled back from the center section of the frame 34 to reveal therebeneath a reproducing fluid containing means such as an inked -or chemically treated pad 56 which supplies'the necessary ink or chemicals to reproduce the writing, etc. marked on the master copy 40. In the case of an inked pad, one composed of ink-impregnated plastic or rubber is preferred in that the pad lasts long and requires little attention. As will be noted, the master copy 40 includes on each end thereof a reinforced section 58 having a plurality of spaced-apart apertures therethrough.'The distance between the apertures on the edge of the master copy is equal to the distance between the studs on the movable portion 57 of clamp 36 so that the studs 38 may be inserted through the apertures ofthe master copy, thereby to hold the master copy securely to the inked pad.

The master copy is preferably of the well known type including a waxed surface. When the surface is marked on wax it is removed in the marked area to allow a fluid such as ink or a chemical to pass therethrough. The passage of the ink, etc.- through the markings on the master copy serves to reproduce the markings on a sheet of paper, etc. adjacent the master copy on the side thereof opposite the inked pad. I

For purposes of affording a more complete understanding. of the invention, it is advantageous now to provide a functional description of the mode in which the component parts thus far described cooperate.

The copying device, as it appears in FIG. 1, is carried by means of handle 18 to a location where it is to be used. The device is placed on the lower section or base 14 as shown in FIG. 1, the clasp 21 is released, and lid or cover 16 is removed entirely or moved to an open position, as shown in FIG. 2.

When the lid has been opened, plate 20 is revealed. A supply of master copies, preferably of the type discussed heretofore, is provided within the case 12. One of such copies is placed on the center section of the plate member 20 and is clamped at opposite sides thereof by means of clamping strips 26. The plates may be removed from the lower section 14, and

markings to be reproduced may then be made on the master copy while it is secured to the center section of the plate.

Subsequent to the completion of the preparation of the master copy, i.e. in some cases a backing sheet must be removed therefrom), the master copy is reversed and placed onto the inked or chemically treated pad 56 mounted on frame 34. The end apertured sections 58 of the prepared master copy are positioned over the stationary clamping portions 54 of clamps 36 with the apertures 59 of the clamping portions being aligned with the apertures in the end sections 58. Upper, hingedly mounted portions 57 of the clamps 36 are then lowered so that respective studs 38 thereof are inserted through respective apertures in the end sections of the master copy and into the lower portions 54 of the clamps (FIG. 6). Locking arms 42 for respective clamps 36 are pivoted into position thereover, thereby to secure the master copy on the pad 56 as shown in FIG. 4.

After the master copy is in position, a blank sheet of paper, upon which the written or other material is to be reproduced, is mounted on plate 20 in the same manner as the master copy was originally mounted thereon. The plate, with the blank sheet thereon, is placed sheet side down onto the master copy held over the pad 56, as shown in FIGS. 79. A roller 60, if available, may be used to press against the plate 20, and hence to press the blank sheet mounted thereon firmly and evenly against the inked master copy. If a roller is not available, this may be accomplished manually. Thus, as shown in FIG. 9, the blank sheet of paper 62 is pressed against the marked master copy 40 and, due to the pressure, ink or a chemical, as the case may be, flows through the markings on the master copy to the blank sheet of paper, whereby, if ink is used, the ink reproduces the markings on the blank sheet. Alternatively, the sheet may have a chemical therein which will react with a chemical in the pad to cause the markings to appear. As will be appreciated, chemicals in the pad can be chosen to avoid smearing of the fingers which sometimes happens with ink.

The above may be repeated again and again, each time using a fresh blank or chemically treated sheet of paper, as the case may be, mounted on the plate 20, until the required number of copies is made.

Thus, the device according to the invention provides a novel copying apparatus which is easily transported, is compact and easy to use in virtually any situation. The device is especially useful in the field or while traveling, for example, in such places as a train, airplane, or the like.

While a particular embodiment of the invention has been shown, it should be understood that the invention is not limited thereto since many modifications may be made; and it is, therefore, contemplated to cover by the appended claims any such modifications as fall within the true spirit and scope of the invention.
